Advil is a brand name for the drug ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and reduce fever. The recommended dose of Advil is 200-400 mg every 4-6 hours, not to exceed 1200 mg in 24 hours [2]. It is important to take Advil with food or milk to prevent stomach upset and to avoid taking it on an empty stomach [3].

According to the NHS, ibuprofen should be taken with or after food to reduce the risk of stomach irritation [3]. It is also important to take the medication as directed and not to exceed the recommended dose. Overdosing on ibuprofen can lead to serious side effects such as stomach bleeding, kidney problems, and even heart attacks [3].

It is important to note that Advil is a brand name and may have different dosing recommendations than generic ibuprofen. However, according to Drug Patent Watch, the active ingredient in Advil is ibuprofen and the recommended dose is the same as generic ibuprofen [1].

In summary, Advil should be taken with food or milk to prevent stomach upset and the recommended dose is 200-400 mg every 4-6 hours, not to exceed 1200 mg in 24 hours. It is important to follow the dosing instructions and not to exceed the recommended dose to avoid serious side effects.
